This application claims priority to U.S. Provisional Patent Application Ser. No. 62/748,454 filed on Oct. 20, 2018 which is incorporated herein in its entirety by this reference thereto.

FIELD OF THE INVENTION

The disclosed device concerns curtain rods. More particularly, it relates to a motorized curtain rod system which is assemblable in a modular fashion from a worm screw drive member formed to length from a plurality of worm screw segments positionable within a housing surrounded by a supporting curtain rod.

BACKGROUND OF THE INVENTION

For centuries, window coverings, such as curtains, hanging shades, and draperies and the like have been employed in homes and offices. Such are used for many purposes such as for the provision of decoration, privacy, and to limit or filter the light entering a window into a room or building. Whether employed for functional or aesthetic purposes, such window coverings conventionally have an open position where they are retracted and a closed position where they have been drawn to cover the window entirely. When used to adjust or filter the amount of light entering a room, such window covering can be located to an infinite number of positions between the retracted and closed positions.

In addition to being locatable to an infinite number of positions for light transmission purposes and privacy, there are also an infinite number of window coverings conventionally available for this purpose. For brevity curtains is a term employed herein for such window coverings and as so used is intended to describe and define any and all of these types, forms and window covering designs including blinds, shades, draperies, and the like, which are mounted in an adjustable sliding position on a curtain rod.

Conventionally, such curtains are engaged to hang in a sliding engagement with a curtain rod. The curtain rod is positioned adjacently above the window to be covered by the drawn curtains. Such curtain rods are held to the wall in a position spaced from the wall and underlying window by mounting brackets. In use, the supported curtains in this sliding engagement to the curtain rod may be pulled or drawn between the retracted position covering or adjacent one or both sides of the window and a closed position. The curtains may be drawn to completely cover the window to block light and/or provide privacy to the occupant of the room, they may be moved to the retracted position providing the most light transmission into the room, or they may be drawn to any of an infinite number of positions therebetween.

The vast majority of such curtain rod and hanging curtain systems are manually operated. Users will either pull or push a leading edge of the sliding-engaged curtain or curtains to and between the retracted and closed positions.

The system disclosed herein provides a motorized curtain hanging and positioning system, which employs a segmented drive rod allowing for easy installation to windows of varying width. Once installed and engaged to the desired curtain, it may be remotely activated to move the hung curtain or curtains between the retracted and closed positions in front of the chosen window.

The forgoing examples concerning curtain rod hanging systems and issues regarding such, are intended to be illustrative and not exclusive, and they do not imply any limitations on the invention described and claimed herein. Various other limitations of the related art are known or will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.

SUMMARY OF THE INVENTION

The system herein provides a solution to the shortcomings of conventional powered and non powered curtain rods through the provision of and easily-assembled electric powered curtain rod support system.

In all modes, the system employs a support rod adapted for engagement of a curtain therewith which is moveable between a retracted position and closed position. The system is rendered especially adaptable to the required length for an individual window through the provision of components which may be trimmed for length and then assembled to form the curtain support device.

A curtain rod having axial passage therein, is configured for the positioning of a sleeve therein once both have been sized according. The sleeve has a plurality of ribs radially projecting therefrom to distal ends which contact an interior wall of the curtain rod which defines the axial passage. These ribs hold the sleeve in operative positioning with a sleeve slot aligned with support member slot.

An axial passageway running the length of the sleeve and in communication with the sleeve slot, is sized for operative rotation of an elongated drive member therein. This drive member has a threaded exterior in the form of a worm screw drive member which engages with the mating recesses in a body of one or a plurality of powered support carriers. Support members engaged to the body of each powered carrier, project through both the sleeve slot and the support member slot and extend its distance from the exterior wall of the support member. The distal end of each support member is configured to engage with the leaded end of a respective curtain hung from the support member. Conventional, sliding, non powered support members engage with the support member to hold the weight of the supported curtain between the leading end and opposite end.

Particularly preferred in all modes of the system herein, are drive member segments, which may be assembled to form a worm screw drive member of a length appropriate for the window and curtain of choice. Also particularly preferred is the configuration of the drive member with a double helix or dual start formation of the formed worm screw type threaded exterior. Such is preferred for the significant increase in speed of the opening and closing of an attached curtain, and for the dual engagement with separate great tracts on the drive member with mating recesses formed in the body of the powered carriers. This dual helix, dual thread engagement, imparts additional torque to the powered carrier to move it along the drive member, and provides a stronger engagement and backup should one of the threads on the elongated member become damaged since the other will continue to translate the powered carrier and the curtain hung from the support rod.

One, or a plurality of electric motors, are operatively connected to the respective assembled and operatively-positioned drive members employed on a support rod. Power for each such electric motor may be provided by a battery engaged to the support rod and/or by AC power from the building. For dual curtains, which close at a central location on a window, two drive members may be employed with one being a right handed dual helix thread and the other being a left handed dual helix thread configuration. Such allows for the curtains to translate toward each other during closing and away from each other during opening of the hung curtains.

Where multiple curtains are hung from multiple assembled support rods, a controller may be employed to concurrently open and close all of the multiple curtains. Using a feedback circuit and monitoring of the electric current used by each electric motor in the plurality, and software adapted to the task, the controller can control the speed of each respective motor in the plurality, to cause each respective curtain to reach its open or closed position at the same time. The software on the controller will learn when each curtain reaches its fully closed or open position by monitoring the electric current used in each motor, which will rise significantly once a curtain reaches a maximum point of closing or opening since the motor will slip on a clutch, but concurrently show a peak current use. By monitoring each motor to ascertain the time needed for translating to reach each open and closing peak, the software on the controller will adapt and change the speed of each motor in the plurality to cause them to all reach the retracted or open position and the closed position at once.

DETAILED DESCRIPTION OF THE INVENTION

In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms refer to the device as it is oriented and appears in the drawings and are used for convenience only and such are not intended to be limiting or to imply that the motorized curtain rod system herein disclosed has to be used or positioned in any particular orientation.

Now referring to drawings in FIGS. 1-16, wherein similar components are identified by like reference numerals, there is seen in FIG. 1, the curtain rod system 10 herein in a fully assembled configuration ready for sliding positioning of a curtain in a sliding engagement (not shown but well known, hereon. Conventionally, such curtains employ clips or non driven carriers which slide upon the exterior of a support rod 12 or as shown in FIG. 15, the non driven carriers 14 slide on a race 16 formed on the support rod 12. Mounts 18 conventionally hold the support rod 12 elevated and spaced from a wall to which the mounts 18 engage.

Shown in FIG. 2 is an exploded view of the components of the system 10 used in all modes such as shown in FIGS. 3-5. As shown, the support rod 12 has an axial passage 20 communicating therethrough between a first end and second end. A sleeve 22 is sized for positioning within the axial passage 24 and has an axial passageway 24 communicating therethrough sized of operative rotation of one or a plurality of drive members 26 therein. As described below, the drive member 26, has a worm screw 28 threaded exterior. Each drive member 26 is engaged with a powered carrier 30 having a body 31 having a complimentary threaded cavity 32 running therethrough whith threads which are complimentary to the worm screw 28 on the threaded exterior of the drive member 26.

Support members 34 project from the body 31 of the powered carrier 30 and extend through a sleeve slot 36 communicating with the axial passageway 24 of the sleeve 22, which aligns with a rod slot 38 communicating through the sidewall 39 forming the support rod 12 with the axial passage 20 thereof. Ribs 40 extending from the exterior of the sleeve 22 may be provided to engage with the axial passage 20 to hold the sleeve 22 operatively therein.

Also shown in FIG. 2, and other figures herein, an electric motor 42 is connected with one end of the drive member 26 and provides a powered rotation thereof when energized by electric power provided by a battery 44 and/or a connection to a power supply or building AC power. As noted below, a remote control communicating with a controller is preferred to switch close a circuit to connect electric power to the motor 42 to rotate. The motors 42 are reversible in rotating direction to thereby cause the engaged drive member 26, to rotate in one direction to pull the curtain engaged with a powered carrier 30 in the open or closed direction for that curtain. Also shown in FIG. 2, two drive members 26 with one having a worm screw 28 drive exterior being a left hand screw configuration and one being a right hand screw configuration. Thus, when one motor 42 rotates both of the drive members 26, the curtains connected with a respective powered carrier 30 engaged thereon, will move to close and open at the same time, in reverse directions. Spacers 46 may be positioned at opposing ends fo the sleeve 22 and have openings therein for engagement of the motor 42 with one end of the drive member 26.

Shown in FIG. 3 is a cut-away view of the curtain rod system 10 as shown in FIG. 1. As depicted, the drive member 26 is formed with the worm screw 28 drive exterior where one half is right hand threaded and the opposite half is left hand threaded and the two halves are joined by a connector. This mode of the system 10, as noted, can employ a single motor 42 which connects during use, to electric power such as a battery 44. Using a controller either built into the motor 42, or a dedicated controller as in FIG. 14, the motor 42 can be activated to rotate in one or the other of two directions, thereby rotating the engaged drive member 26, to translate the respective engaged powered carriers 30 concurrently toward or away from each other.

FIG. 4 depicts a bottom view of a typical mode of the curtain rod support system 10 herein in all modes, whether carrying a single curtain to open and close, or two curtains toward and away from each other. As shown, the support members 34 engaged to respective powered carriers 30, project through the rod slot 38, which as noted is aligned with the sleeve slot 36 of the sleeve 22 operatively positioned within the axial passage 20 of the support rod 12. Also shown through the aligned slots are the battery 44 which may be operatively engaged to provide power to the motor 42 using wiring.

Depicted in FIG. 5 is a cut-away view of a mode of the system 10 herein which operates in the same fashion of that of FIG. 1. In this mode of the system 10, the drive member 26 is formed with only a right or left handed worm screw 28 thereon which engages a complimentary threaded passage 32 of a single powered carrier 30. The motor 42 is engaged to one end of the formed drive member 26, and is switchable between rotation directions by a controller and remote control or wired switch, to move the powered carrier 30 and connected curtain thereto, between the open and closed positions.

As noted, in the particularly preferred mode of the system 10 herein, such as shown in FIGS. 6 and 8, the device is configurable for length on site, by trimming the length of the support rod 12, and the sleeve 22 and forming the drive member 26, from segments 27 which engage at abutting ends to form the elongated drive member 26. Each segment 27 has mating connectors 50 at each end configured to engage the mating connector 50 of the adjacent segment 27 forming a drive member 26. Thus the user can assemble the segments 27 to form the proper length drive member 26 needed. The segment 27 on the end of the formed drive member 26, opposite that which operatively connects to the motor 42, can also be trimmed to reach a desired drive member 26 length.

Additionally, in all modes of the system 10, the motor 42 will have a mating connector 50 which will engage with the mating connector 50 on an engagement end of the drive member 26 be it from segments 27 or a single piece. Such a mating connector 50 may be shown as the depicted post 52 engageable in a recess 54 shown in FIGS. 7-8.

Also shown in FIG. 7 and in FIG. 8, are an especially preferred configuration of the drive member 26, whether formed in a single section or formed of a plurality of drive segments 27. As shown, the drive member 26, has two independent worm screw 28 threads 58 and 60, projecting therefrom in a double helix configuration. Each projecting thread has a respective starting point 56 at one end of the formed drive member 26 whether formed of segments 27 such as in FIG. 8, or one piece as in FIG. 7 or FIG. 5.

This double helix of parallel helical worm screw 28 threads, thus provides two different projecting threads for engagement within the complimentary threaded cavity 32 of a powered carrier 30 which would also have two threads and two thread recesses therebetween. This double helix winding provides a significant increase in the speed in which the powered carrier 30 translates in both directions upon the drive member 26. Additionally, the two individual worm screw threads such as a first helical thread 58 and a second helical thread 60, both independently impart power during rotation of the drive member 26, to the powered carrier 30. Thus, torque force is more equally communicated and should one of the two helical threads 58 or 60. Further, should either the first helical thread 58 or second helical thread 60 become damaged, the system 10 will still operate since the other of the two helical threads 58 or 60 will still be engaged with the complimentary threaded cavity 32 which also has two independent helical threads and passages therebetween.

Shown in FIG. 9 is the sleeve 26 employed in the system 10 herein in all modes. As noted, the sleeve 26 has an exterior circumferential surface 62 which contacts with an interior surface 19 of the support member 12 defining the axial passage 20 such as shown in FIG. 2. Preferably, this exterior circumferential surface 62 is formed at the distal ends of a plurality of ribs 40 extending from the exterior of the wall 64 of the sleeve 22 which surrounds the axial passageway 24. This rib 40 configuration is preferred as it provides pathways 65 between the ribs 40 where wires may communicate between the motor 42 on one end of the support member 12 and a battery 44 on the other when configured as such, or for circuits communicating with a controller and the motor or motors to control multiple support rods 12 as in FIGS. 13-14.

In FIG. 10 is shown an end view of the sleeve 14 operatively engaged within the axial passage 20 by a plurality of ribs 40 projecting from the exterior of the wall 64 thereof. Also shown is the mating connector 50 on one end of the drive member 26 which is rotationally engaged within the axial passageway 24 of the sleeve 22. As noted a motor 42 will have a complimentary mating connector 50 to thereby engage to the drive member 26. As also shown, the powered carrier 30 has a support member 34 which projections through the sleeve slot 36 and the rod slot 38.

In FIG. 11 is shown the sleeve of the system 10 such as in FIG. 10 having the drive member 26 operatively positioned within the axial passageway 24 running a length of the sleeve 22. Also shown are the preferred ribs 40 which form pathways 65 therebetween with the sleeve 22 operatively engaged within the axial passage 20 of the support rod 12.

Shown in FIG. 12 is a perspective end view of the sleeve of the system 10 similar to FIG. 10, in a particularly preferred mode of engagement with the interior surface 19 of the support rod 12. This mode is favored because it maintains the sleeve slot 36 aligned with the rod slot 38, and prevents rotation of the sleeve 22 within the axial passage 20 which might be caused by the force of rotation of the drive member 26. As shown, recesses 67 are formed into the interior surface 19 of the wall 64 of the support rod 12, into which the ribs 40 engage. So engaged, the ribs 40 maintain the sleeve 22 in a fixed position within the axial passage 24 of the support rod 12.

FIG. 13 shows an overhead view of a mode of the system 10 herein showing that it is configurable to open and close multiple curtains hung from a plurality of support rods 12. Each support rod 12 will have an appropriate drive member 26 positioned therein to translate a curtain engaged to that respective support rod 12. While shown at angled positions, the individual support rods 12 can be in any orientation to the other, as this figure is to show the system can be used to control multiple curtains.

FIG. 14 shows the system 14 having a controller 47 which may be remotely activated by a wireless remote or a smart phone or the like by wireless communication, or a wired switch. In this mode, a single support rod 12 configuration with one curtain can be so controlled, and it should be noted the controller 47 may be a component engaged in the motor 42.

As noted above, when multiple curtains are hung from multiple assembled support rods 12, the controller 47 may be employed to concurrently open and close all of the multiple curtains. For example, using a feedback circuit 43 or the like, monitoring the electric current used by each electric motor 42 in the plurality, and software adapted to the task, the controller 47 can control a rotation speed of each respective motor 42 in the plurality, to control the translation of teach respective powered carrier 30 to reach a respective open or closed position of an engaged curtain at the same time. The software on the controller 47 is configured to learn when each curtain reaches its fully closed or open position by monitoring the electric current used in each motor 42, which will rise significantly once the powered carrier 30 engaged to a curtain reaches a maximum point of closing or opening. This is because the motor 42 will slip on a clutch but concurrently show a peak current use. The software is configured for calculating appropriate motor speeds to achieve appropriate translation speeds of the individual powered carriers 30 to cause reaching concurrent closed and open positions at the same time.

FIG. 15 depicts a mode of the system 10 herein wherein the support member 12 additionally includes a race 16 for rolling or sliding of the non powered curtain carriers 14 thereon. As shown, the system 10 is configured and operates in the same fashion as the other modes of the system 10 noted above, but for the non driven carriers 14 running on a race 16 or the like, rather than on the exterior surface of the support rod 12.

Shown in FIG. 15A is a perspective end view of the powered carrier 30. As noted above, the powered carrier 30 is operatively engaged with the drive member 26 by the complimentary threaded cavity 32 running axially through the body 31 of the powered carrier 30. The complimentary threaded cavity 32 will have threads formed on the sidewall thereof which are complimentary and operatively engaged the threads upon the drive member 26. As noted and shown, preferably the configuration of the threads formed on both the drive member 26 and the complimentary threaded cavity 32 are in the form of a worm screw 28 with two separate double helix configured threads. This, as noted, speeds up the translation of the powered carrier 30 and engaged curtain, and doubles the contact area between the powered carrier 30 and drive member 26 to communicate torque, and provides the ability to work with only one of the threads should one become damaged.

Additionally shown in FIG. 15A, is a releasing connector 35 which engages with a hook or similar support on the lead end of a curtain used herewith. The releasing connector 35 as shown, has a rotating member 37 which locks in place to hold the curtain hook or support, but easily rotates open to disconnect the powered carrier 30 from the curtain should power to the motor 42 fail. This allows the user an easy means to disconnect the curtain from the powered carrier 30 and pull it manually, if required.

Finally, FIG. 16, depicts typical steps in configuring and assembling the system 10 herein to a length adapted in size for a window where the system is to be installed.

It should be noted that any of the different depicted and described configurations and components of the motorized curtain rod system herein, can be employed with any other configuration or component shown and described as part of the device herein.
